Moss Growing On Shingles Of Roof

Hello wood rot and leaks.

Moss growing on shingles of roof. Once the spores get on the roof they gather in the spaces between shingles and grow into thick spongy moss. Over time moss can also work its way under shingles lifting them up. The seams between the shingles and the shingles edges also develop moss because they tend to be especially shaded. This thin layer on the top of the shingles expands and becomes wide thick and mat like.

Moss keeps the roof wet. Moss starts as a thin green layer on and between shingles but then it proceeds to lift those shingles up as it grows allowing water to seep underneath. You can apply the copper solution to new roofs to prevent any growth for a number of years. Moss growing on a roof may or may not be considered attractive or quaint but there is no doubt that extensive moss on a roof can seriously damage the roof by growing under and raising or loosening.

This moisture increases the weight of the roof which increases the risk of collapse decay leaks and water damage. Since moss thrives in damp environments areas of the roof that get the least amount of direct sunlight like north facing sections or areas shaded by tree limbs make an ideal place for it to grow. The resulting constant exposure to water can degrade shingles. Moss and green algae require dead organic matter for nutrients so you can prevent their growth by blowing off the shingles to remove junk from trees that tend to accumulate between the tabs.

Moss on a roof begins with a thin dusting of green that you may notice only from low angles. Moss isn t just attracted to moisture. Moss growth will also interfere with proper drainage of water off the roof as water needs to trickle through or around the moss instead of running straight down to the gutters. This lack of drainage not only helps the moss grow and thrive but also may damage your roof because it increases the risk of water getting under the shingles.

Once under the shingles the moisture can reach the underlying structure.
